Engine Exhaust, some of its constituents, and
certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other repro-
ductive harm.
Battery posts, terminals and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the State of California to cause
cancer and birth defects or other reproductive
harm. WASH HANDS AFTER HANDLING.
NOTE: This unit is equipped with an internal combustion engine
and must not be used on or near any unimproved forest-covered,
brush-covered or grass-covered land unless the engine's exhaust
system is equipped with a spark arrester meeting applicable local
or state laws (if any). If a spark arrester is used, it must be
maintained in effective working order by the operator.
In the State of California, the above is required by law (Section
4442 of the California Public Resources Code). Other states may
have similar laws. Federal laws apply on federal lands. See a
Sears Service Center for a spark arrester for the muffler.
In some areas, local law requires the use of a resistor spark plug
to control the ignition signals. See a Sears Service Center for a
resistor spark plug for the engine.
NOTE: Actual sustained horsepower will likely be lower due
to operating limitations and environmental factors.

Safe Operation Practices for Ride-on Mowers
WARNING: This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the
following safety instructions could result in serious injury or death.
I. General operation 21
1. Read, understand and follow all instructions in the Instruction
Book, on the machine, the engine and with any attachments be-
fore starting.
2. Only allow responsible adults, who are familiar with the instruc-
tions, to operate the machine.
3. Clear the area of objects such as rocks, toys, wire, etc., which
could be picked up and thrown by the blade.
4. Be sure the area is clear of other people before mowing. Stop
the machine if anyone enters the area.
5. Never carry passengers.
6. Turn off power to the blades or any attachments before backing
up. Do not mow in reverse unless absolutely necessary. Always
look down and behind before and while backing.
7. Be aware of the mower discharge direction and do not point it
at anyone. Do not operate the mower without either the entire
grass bagger or the mower guard in place.
8. Slow down before turning.
9. Never leave a machine unattended with the engine running. Al-
ways turn off the blade(s), set the parking brake, stop the en-
gine and remove the key before dismounting.
10. Turn off power to attachment(s) when transporting or not in use.
Turn off the blade(s) when not mowing.
11. Stop the engine before removing the grass bagger or unclog-
ging the chute.
12. Mow only in daylight or good artificial light.

F-040607L
II. Slope operation
Slopes and rough terrain are major factors related to loss-of-
control and tip-over accidents, which can result in severe inju-
ry or death. ALL slopes require extra caution. If you cannot
back up the slope or if you feel uneasy on the slope, do not mow
it. See the "Slope Guide" in the back of this book to check for
safe operation.

Grass bagger components are subject to wear, damage and
deterioration, which could expose moving parts or allow objects
to be thrown. For storage, always make sure the grass bag is
empty. Frequently check components and replace with man-
ufacturer's recommended parts when necessary.
Mower blade(s) are sharp and can cut. Wrap the blade(s) or
wear gloves and use extra caution when servicing them or the
blade housing area.
10.
Check the brake operation frequently. Adjust and service as re-
quired.
11.
Wait for all movement to stop before servicing any part of the
unit.

PREPARATION
HOW TO PREPARE THE ENGINE
NOTE: The engine was shipped from the factory filled with oil.
Check the level of the oil. Add oil as needed.
Before you use the unit, read the information on safety, operation,
maintenance, and storage.
CHECK THE LEVEL OF THE MOWER HOUSING
Make sure the level of cut is still correct. After you mow a short
distance, look at the area that was cut. If the mower housing does
not cut level, see the instructions on "How To Level The Mower
Housing" in the Service And Adjustment section of this instruction
book.
CHECK THE TIRES
Check the air pressure in the tires. Tires with too much air pressure
will cause the unit to ride rough. Also, the wrong air pressure will
keep the mower housing from cutting level. The correct air pressure
(PSI) is as follows. Semi-pneumatic front tires do not require air.
Front Tires 22 PSI (1.5 BAR)
Rear Tires 14 PSI (! BAR)
IMPORTANT! BEFORE YOU START MOWING
Check the engine oil,
Fill the fuel tank with gasoline.
Check the level of the mower housing,
Check the air pressure of the tires.
Make sure the battery cables are attached.

OPERATING TIPS
OPERATION
Check the attachment clutch for correct adjustment. For the
blade(s) to disengage correctly, the adjustment must be cor-
rect.
2.
Before you use the unit, check the oil in the engine and add oil
if necessary.
3.
If the engine will not start, first make sure the wire is attached
to the spark plug.
4.
Make sure all the belts are inside all the belt guides. See the in-
structions on how to remove and install the motion drive and
mower drive belts.
MOWING AND BAGGING TIPS
1. For a lawn to look better, check the cutting level of the mower
housing. See "How To Level The Mower Housing" in the Ser-
vice And Adjustment section.
2. For the mower housing to cut level, make sure the tires have
the correct amount of air pressure (PSI).
3. Every time you use the unit, check the blade. If the blade is bent
or damaged, immediately replace the blade. Also, make sure
the nut for the blade is tight.
4. Keep the blade(s) sharpened. A worn blade(s) will cause the
ends of the grass to turn brown.
5. Do not cut or bag grass that is wet. Wet grass will not discharge
correctly. Let the grass dry before cutting.
6. Use the left side of the mower housing to trim near an object.
7. Discharge the cut grass onto the mowed area. The result is a
more even discharge of cut grass.
8. When you mow large areas, start by turning to the right so that
the cut grass will discharge away from shrubs, fences, drive-
ways, etc. After one or two rounds, mow in the opposite direc-
tion making left turns until finished (Figure 11).
9. If the grass is very high, cut two times to decrease the load on
the engine. First cut with the mower housing in the highest posi-
tion and then lower the mower housing for the second cut.
10. For better engine performance and an even discharge of the
cut grass, always operate the engine with the throttle in FAST
position.
5. Before you make an inspection, adjustment (except for the car-
buretor) or repair, make sure the wire from the spark plug is dis-
connected.
6. Make sure the seat switch wire is connected. If the wire is not
connected, the engine will not start.
7. For longer life of the battery, charge the battery every three
months.
8. Use the shift lever to change the ground speed, not the throttle
control.
9. Belt noise can occur when the blade or clutch is engaged. This
noise is normal and does not affect the operation of the unit.
10. To move forward, always release the clutch/brake pedal slowly.
11. When you use a bagger, operate the engine with the throttle in
FAST position and the shift lever in first or second gear.
12. For better cutting performance and a quality cut, mow with the
shift lever in one of the slower speeds.
13. After each use, clean the bottom and top of the mower housing
for better performance. Also, a clean mower housing wil! help
prevent a fire.

Figure 11
MULCHING TIPS
When you use a mulcher attachment, the grass is cut into very small
pieces. These small pieces will quickly break down. Because the
nutrients are returned to the soil, the lawn will need less fertilizer. Too
correctly mulch the grass, follow the steps below.
1. Set the throttle in the FAST position. Operate the mower at a
slower ground speed. If ground speed is too fast, the grass will
not have an even cut.
2. Keep a sharp edge on the blade. A blade that is not sharp will
cause the ends of the grass to become brown.
3. Make sure the grass is dry. Wet grass is difficult to cut.
F-040607L 17
Set the height of the mower housing so that only the top third
of the grass is cut. If the grass is too high, set the height of the
mower housing to the maximum height. Then, lower the mower
housing for the second cut. Also, instead of using the full width
of the mower housing, mulch at half the width.
5.
Clean the bottom of the mower housing. Grass and other debris
can keep the mower from working correctly.
6.
If the grass grows fast, mulch more often.
7.
If an area needs improvement, mulch a second time.

GENERAL RECOMMENDATIONS
1. The owner's responsibility is to maintain this product. This will
extend the life of the product and is also necessary to maintain
warranty coverage.
2. Check the spark plug, drive brake, lubricate the unit, and clean
the air filter once a year.
3. Check the fasteners. Make sure all fasteners are tight.
4. Follow the Maintenance and the Service And Adjustment sec-
tion to keep the unit in good operating condition.
WARNING: Before you make an inspection, adjust-
,_ ment, or repair to the unit, disconnect the wire to the
spark plug. Remove the wire from the spark plug to
prevent the engine from starting by accident.
CHECK THE TIRES
Check the air pressure in the tires. Tires with too much air pressure
will cause the unit to ride rough. Also, the wrong air pressure will
keep the mower housing from cutting level. The correct air pressure
(PSI) is as follows. Semi-pneumatic front tires do not require air.
Front Tires 22 PSI (1.5 BAR)
Rear Tires 14 PSI (! BAR)

HOW TO SHARPEN THE BLADE
WARNING: Vibration can be caused if the blade is
not correctly balanced or if the blade is damaged.
A blade that is damaged with cracks can break and
cause an accident.
Keep a sharp edge on the blade. A blade that is not sharp will
cause the tips of the grass to become brown.
1. Sharpen the blade two times a year or every 25 hours.
2. Remove the blade according to the instructions in "How To
Remove And Install The Blade".
3. Clean the blade with a brush, soap and water. Check the
blade. Look for cracks, nicks, or other damage. Replace a
badly worn or damaged blade with an original equipment
blade. See a Sears Service Center in your area.
4. Sharpen the blade with a file (Figure 14). Make sure you
keep the original bevel angle.
5. Make sure the blade is balanced. Use a screwdriver and
hold the blade parallel to the ground (Figure 14). A blade
that is balanced will stay parallel to the ground. If the blade
is not balanced, the heavy end will rotate toward the ground,
Sharpen the heavy end until the blade is balanced.
6. A new blade will cut better than a badly worn blade. Every
three years, have a qualified service person inspect the
blade or replace the old blade with an original equipment
blade.
7. Assemble the blade according to the instructions "How To
Remove And Install The Blade".

HOW TO ADJUST THE CARBURETOR
Differences in fuel, temperature, altitude or load may require minor
carburetor adjustment. The air cleaner and its cover must be
assembled to carburetor before starting engine.
The carburetor on this engine is equipped with an idle mixture valve
with a limiter (see inset), which allows some minor adjustment, and
an idle speed adjustment screw.
1. To adjust idle speed, start engine and warm up about 5 minutes.
2. With engine running, put the remote throttle control in SLOW
position (see Figure 20).
3. Rotate the carburetor throttle control lever against the idle
speed screw and hold it (see Figure 22). Then, turn the idle
speed screw to obtain 1750 rpm (use a tachometer).
4. Rotate the idle mixture valve full travel clockwise and then
counterclockwise.
NOTE: DO NOT remove limiter caps. DO NOT force beyond
limits.
5. Then, position idle idle mixture valve in middle of travel.
F-040607L 24
6. Move the remote throttle control to the FAST position. The
engine should accelerate smoothly. If it does not, adjust the idle
mixture valve counterclockwise 1/8 turn.
NOTE: Engines operated at approximately 3000 to 5000 feet (900
to 1500 meters) above sea level may require a high altitude
carburetor nozzle. If erratic performance is observed, contact a
Sears Service Center for cost to install or to purchase a high
altitude carburetor nozzle.
